Is there a way to re-install the stock module from the command line. I can no longer log into openerp as I get a pop up after I enter my password saysing openerp server error and it ends with ValueError: No such external ID currently defined in the system: product.product_uom_categ_kgm

I am assuming it has something to do with uom categories and units - so I was hoping re-installing the stock module would fix this? I was wondering how I would go about doing it from the command line in ubuntu / linux

ANy help would be appreciated,

thanks
